Serial Miniature LCD Module - 1.44" (uLCD-144-G2 GFX)

Description: The µLCD-144-G2(GFX) is a compact and cost effective display module using the latest state of the art LCD (TFT) technology with an embedded GOLDELOX-GFX2 graphics processor that delivers ‘stand-alone’ functionality to any project. Powerful graphics, text, image, animation and countless more features are built inside the GOLDELOX-GFX2 chip.

The module is designed to work out of the box and you are now ready to write your code in 4DGL (a high level 4D Graphics Language) using the 4DGL-Workshop3 IDE (editor, compiler, linker and downloader). This will save weeks even months of development time on your next embedded graphics project.

4DGL is a graphics oriented language allowing the developer to write applications in a high level language, syntax similar to popular languages such as BASIC, C and Pascal. The module offers modest but comprehensive I/O features that can interface to serial, analogue, digital, buttons, joystick, sound generation and Dallas 1-wire devices. In short, the µLCD-144-G2(GFX) offers one of the most flexible embedded graphics solutions available.

Note: This module is shipped with the “GFX” firmware. Either firmware can be loaded onto the device, however. For more information on reloading the firmware, see the 4D Systems product page below. Also, It’s been brought to our attention that trying to program the 4D screens using an FTDI breakout can damage the driver. You’ll need to use the FT232RQ USB to Serial which you can find in the related items below.

ViSi-Genie isnt compatible with the Goldelox Processor which is used on this product, only for Picaso products, so the library you have referenced isnt relevant. There are 3 other environments to program with, you can use any of those. Go to the 4D website and have a read, its on their product pages and the Workshop4 Product Page.

Kinda strange because they do have that information in the product brief, section 10, Mechanical Dimensions - but apparently didn’t re-use it for the datasheet (which should be authoritative, but that as an aside).

The holes are 2mm diameter, centers of the holes are situated 1.5mm from each closest edge.

why the Pmmc loader always come out a comment “unexpected response from display -0” when i change the firmware form GFX to SGC. I just followed the tutorial in this website:http://tronixstuff.wordpress.com/2011/02/18/tutorial-arduino-and-tft-lcd/
but it didn’t works.Help!

NO! You cannot do this easily. The module is designed to be a standalone and though 4Dsystems says they support the serial interface, there is no documentation any longer on it. In addition, serial comms do not work with these displays as described in the older manuals. They are BASICALLY USELESS unless you want to just draw pretty pictures and build a system around the Goldelox. IT WILL NOT SLAVE to another processor.

I programmed successfully several 4D’s uOLED-96 with Sparkfun FTDI breakout board a lot of times without any damages. But we must remember that these displays have 3.3 volt signal circuitry (RX & TX) and need about 1 kOhm resistor on RX pin if connect to TX of 5 volt microcontroller or another device.

RX pin is 5V tolerant , Reset pin is not ! ( it has an internal pullup to 3.3V )
You can control the reset with a micro , but do not feed it with 5V , only 0V , 4148 in series to let only gnd pass could be the easiest solution … or toggle the micro pin only to 0 or no pullup float .
